The bushings will be prevented from slacking off by means of jam nuts 34.

To establish contact between a source of electrical power and the unit, I provide contact brushes 35 which are spring seated in a pair of nipples 36 screwed into the yoke to one side of one of the collars 32 and in alignment with the slip rings I8 and I9.

The terminals 22 upon the element casings I and H are in pairs. This is to enable a parallel connection to be used if desired. When a series connection is used, current passes from the element on one side of the disc to the element upon the other side by means of the beaded leads 31 and 38.

In the drawings, I have shown the resistance wires as spirally formed within the element casings l0 and II. Obviously, however, they may be Wound in any manner therewithin which I may elect, and it will be noted that these wires within the element casings are insulated therefrom by means of heat conducting insulation 39 shown in Fig. 6.

The reason for the provision of heat radiation discs I2 is in order that the heat emanating from the elements It! and Il may be all directed upwardly so as to concentrate an intense heat upon the incised branding surface. Due to the fact that the outer faces of these heat radiation discs l2 and I3 bear against insulating discs l4 and I 5, the heat cannot dissipate in any direction except to the surface of the branding wheel. 5

Since various modifications can be made in the above invention, and many apparently widely different embodiments of same made within the scope of the claim, without departing from the spirit and scope thereof, it is intended that all matter contained in the accompanying specification shall be interpreted as illustrative only and not in a limiting sense and I desire only such limitations placed thereon as are specifically expressed in the accompanying claim.

What I claim as my invention is:

A rotary branding unit heated by electrical conduction comprising a circular heat conducting element, a branding surface surrounding said element, resistances mounted upon both sides of said heat conducting element, heat conduction plates upon the outer side of said resistances, heat insulation members upon the outer side of said plates, a shaft extending through said branding unit, means comprising slip rings and brushes for introducing electric current to said resistances, a yoke surrounding said unit and freely mounted upon said shaft and means for manually operating said unit over the object to be branded.
